Friar's Point, July 2, 1910, male (E. C. Crockett) ; Saltillo, sum- 

 mer, female, collected in the middle of a large swampy woods (T. P. 

 Cassidy) ; Rosebloom, August, 1915, female (Rex Buchanan) ; Green-

 (A. E. Bonnelli) ; Palmyra, July, 1912, five males and five females 

 (R. N. Lobdell). In addition to the above mentioned Mr. Lobdell 

 has personally sent to the writer three males and two females, also 

 some pupae and pupae cases " collected during July at Palmyra Island, 

 Mississippi," which he states is subjected to periods of inundation, so 

 the young insects are evidently able to live in very wet soil. 



Prof. R. W. Harned has contributed the following note : " In regard 

 to the distribution of Tibicen vitripennis I am inclined to think that 

 this insect will only be found on low ground or in swampy places. 

 This insect seems to be fairly prevalent in what is known as the delta 

 section of Mississippi or the Yazoo-Mississippi Delta. This is the 

 alluvial western part of the state. This species is also fairly abun- 

 dant in similar soils in Arkansas and Louisiana. The first time that 

 I ever noticed this species was late in June, 1912. I found them 

 quite numerous in fields at Palmyra Island, south of Vicksburg. I
